In the present study, the extent of costochondral ossification of the first rib was determined from 78 chest roentgenograms of 13 healthy male soldiers subjected to a periodic follow-up. Roentgenography was performed at a mean interval of 2.9 years over a 15-year period. Mean subject age was 24 years at the commencement of the study and 37 years at its termination. Our results show that ossification of the first costal cartilage may start early in adult life and progress at individual rates. The ossification process proceeded from the costal toward the sternal end of the cartilage in an anteromedial direction. The morphological age-related changes ranged from the formation of small osseous islands in the cartilage to a complete ossification between the first rib and the sternum. The main conclusion of the study is that the degree of ossification of the first costal cartilage as an indicator of age does not provide the precision necessary for anthropological or forensic studies.
在本研究中，通过对13名接受定期随访的健康男性士兵的78张胸部X线片进行分析，确定了第一肋肋软骨的骨化程度。在15年的时间里，平均每隔2.9年进行一次X线检查。研究开始时受试者的平均年龄为24岁，研究结束时为37岁。我们的结果表明，第一肋软骨的骨化可能在成年早期就开始，并以个体速率进展。骨化过程从软骨的肋端向胸骨端呈前内侧方向进行。与年龄相关的形态学变化范围从软骨中形成小骨岛到第一肋与胸骨之间完全骨化。该研究的主要结论是，作为年龄指标的第一肋软骨骨化程度，无法为人类学或法医学研究提供所需的精确性。
